ABSTRACT

Embodiments of the present invention provide a method, system and computer program product for multi-flavored software execution from a singular code base. In an embodiment of the invention, a method for multi-flavored software execution from a singular code base is provided. The method includes receiving a request in an interpreter to interpret a version of source code of a computer program the interpreting transforming the source code into byte code executable by a virtual machine. The method thereafter includes responding to the request by performing in the interpreter source code interpretation only of selected portions of the source code being annotated by tags corresponding to the version.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to software versioning and more particularly to deploying different versions of a computer program to different end users.

Description of the Related Art

Traditional software deployment refers to the development and distribution of a computer program that provides one or more functional features upon execution in the memory of a computer. As different functional features are developed, new versions of same computer program are deployed, either as an upgrade for an existing end user or a new purchase for a new or existing end user. At any given moment, the developer distributes only a single, most recent version of the computer program, though prior versions of the computer program remain deployed for existing end users.

Oftentimes, it is desirable to deploy multiple different versions of the same computer program at the same time, each of the versions incorporating a different selection of functional features. In many instances, a basic and advanced version of the same computer program is provided, the cost of both versions varying according to the number and nature of the selection of the functional features. To deploy multiple versions of the same computer program, however, requires multiple different builds of the same computer based upon a single code base.

To address the complexity and inefficiency of deploying multiple different versions of the same computer program, developers build a single deployable computer program with certain functions disabled. Responsive to internal programmatic directives, different ones of the functional features can be enabled or disabled so as to customize the set of functional features. Thus, essentially different versions of the computer program may exist with but a single deployed computer program. Consequently, the size of the executable computer program can be massive in that all possible functional features must be present in the executable object at run-time irrespective of the number of features ultimately selected for use by the end user.

BRIEF SUMMARY OF THE INVENTION

Embodiments of the present invention address deficiencies of the art in respect to application versioning and provide a novel and non-obvious method, system and computer program product for multi-flavored software execution from a singular code base. In an embodiment of the invention, a method for multi-flavored software execution from a singular code base is provided. The method includes receiving a request in an interpreter to interpret a version of source code of a computer program the interpreting transforming the source code into byte code executable by a virtual machine. The method thereafter includes responding to the request by performing in the interpreter source code interpretation only of selected portions of the source code being annotated by tags corresponding to the version. In one aspect of the embodiment, the interpreter is a PHP hypertext processor interpreter. In another aspect of the embodiment, the source code includes multiple portions, each portion having an annotation indicating a particular corresponding version of the computer program.

In another embodiment of the invention, a data processing system is configured for multi-flavored software execution from a singular code base. The system includes a host computing system having at least one computer with memory and at least one processor. The system also includes a virtual machine executing in the memory of the host computing system and an interpreter executing in the virtual machine. The interpreter includes program code enabled to receive a request to interpret a version of source code of a computer program the interpreting transforming the source code into byte code executable by the virtual machine, and to respond to the request by performing in the interpreter source code interpretation only of selected portions of the source code being annotated by tags corresponding to the version.

Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:

FIG. 1 is a pictorial illustration of a process for multi-flavored software execution from a singular code base;

FIG. 2 is a schematic illustration of a data processing system configured for multi-flavored software execution from a singular code base; and,

FIG. 3 is a flow chart illustrating a process for multi-flavored software execution from a singular code base.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention provide for multi-flavored software execution from a singular code base. In accordance with an embodiment of the invention, an instruction is received in an interpreter to interpret source code of a computer program into object code suitable for execution by an underlying operating system. The source code includes programmatic instructions grouped by functionality with selected ones of the grouped functionality being annotated with a tag corresponding to a particular version of the computer program. In response, the interpreter parses the source code and interprets only those portions of the source code with an annotation matching a specified version. In this way, a single code base of the computer program is maintained while still allowing for multiple versioning without requiring a large executable.

In further illustration, FIG. 1 pictorially shows a process for multi-flavored software execution from a singular code base. As shown in FIG. 1, one or more source code files 110 of interpretable source code for a multi-version application are provided. Each of the source code files 110 includes different portions, annotated according to a specified version. Multi-flavored software execution logic 120 receives from an end user a provisioning request 130 to execute a particular version of the multi-version application. The provisioning request 130 particularly specifies a version of the multi-version application.

Thereafter, the multi-flavored software execution logic 120 parses the source code files 110. In doing so, the multi-flavored software execution logic 120 permits the interpreter 160 to interpret only those portions of the source code files 110 that have been annotated with a version consistent with the version specified in the provisioning request 130. Thereafter, the interpreter produces byte code objects 140 corresponding to the interpreted portions of the source code files 110. The resultant byte code objects 140 are then provided to a virtual machine 150 in which the objects 140 are executed in order to present the requested version of the application 170.

The process described in connection with FIG. 1 is implemented in a data processing system. In yet further illustration, FIG. 2 schematically illustrates a data processing system configured for multi-flavored software execution from a singular code base. The system includes a host computing system 210 that includes one or more computers, each with memory and at least one processor. The host computing system 210 is coupled to a source code repository 230 of source code files for a multi-version application. A PHP interpreter 220 executes in the memory of the host computing system 210 utilizing the computing resources both physical and logical of the host computing system 210, and is configured to interpret different specified portions of source code files in the source code repository 230 and to provide resulting byte code over computer communications network 240 to requesting virtual machines 260 executing in respectively different client computers 250.

Of note, the system includes a multi-flavored execution extension 300 to the PHP interpreter 220. The multi-flavored execution extension 300 is included either as part of the program code of the PHP interpreter 220 thereby forming a customized interpreter, or the multi-flavored execution extension 300 is coupled to the PHP interpreter 220 as an extension to the PHP interpreter 220. In either circumstance, the multi-flavored execution extension 300 includes program code that when executed within the memory of the host computing system 210, is enabled to identify a particular version of the multi-version application, to load the source code files in the repository 230 for the application, to select only those portions of the source code files pertinent to the identified version, and to provide those selected portions to the PHP interpreter 220 for interpretation into resultant byte code to be transmitted to a requesting one of the virtual machines 260.

In even yet further illustration of the operation of the multi-flavored execution extension 300, FIG. 3 is a flow chart illustrating a process for multi-flavored software execution from a singular code base. Beginning in block 310, a deployment request is received to provision a version of a multi-version application into a virtual machine of a communicatively coupled client computer. In block 320, the requested version is identified and in block 330, an interpreter is invoked to interpret only those portions of the source code of the multi-version application relating to the specified version in order to produce byte code specified to the specified version of the multi-version application. In block 340, the resultant byte code is selected and provided to the virtual machine in block 350.
